M/D: Smooth, medium body, carbonation is relatively low, alcohol is not apparent. Drinkability is superb for me. Maybe not a surprising good beer in itself, but definitely surprised how good I find this beer (Brewdog seems hit or miss).

Poured a very nice murky copper color with wonderful head and lacing. Excellent scent; very deep malty sweetness -- very thick; excellent bitter tones in the nose, slight jerky tinge, great English hop scent. Very good taste; it has a great thick maltiness throughout with hints of caramel; wonderful hop attributes throughout, especially with the great English hops at the end that stay on the tongue. Fairly thick, but goes down well for a 7+ ABV brew.

, orange tinted honey colored amber being presented in front of me. Very hazy, with the cloudiness no doubt due to the unfiltered nature of it. A nice white head of foam, perhaps two fingers high then came over the top and settled down gradually to just a thin film of lace. Very nice appearance I would have to say. Some decent carbonation could be seen trickling up from the bottom and a good amount of side glass lace was involved as well.

The aroma was pleasant, not as strong as I would have liked, but still pretty decent. There was a nice floral hoppiness, somewhat muted hints of orange and lemongrass with a touch of pine. Decent malt base was apparent as the aroma of bread came through nicely. The flavor followed much of the same, owing that nice light floral hoppiness, but never having enough of it to really push it all the way forward. Nice little bite of bitter on the back of the tongue, and a slightly fruit finish, with apples coming through very clearly, especially in the aftertaste. The Mouthfeel was a little thin, maybe a touch watery, but had more then decent carbonation.

Orange butterscotch colour. Nice head, but fades quickly. Strong hoppy American craft IPA taste, but not over-carbonated. Very tasty. The hoppy aroma reminds me of marijuana (again). Another great BrewDog IPA, and better than Hardcore in my opinion, this isn't sweet, and the alcohol just doesn't seem to be there, yet at 7.1% it clearly is. Nice one.

Pours a remarkably frothy head, off-white and long-lasting. The liquid is a lightly hazed bronze color, and only small, thin wisps of lace are left on the glass.

Aroma is very much to style, but of course with the usual BrewDog twist. (Wouldn't be a BrewDog brew if it didn't have some kind of twist in the structure.) The nose receives a nice dose of musty, buttery, semi-sweet toffee-like malt, with a little bit of butterscotch coming in as well. Hop presence is merely subtle, with the malt being more upfront than a typical IPA, and there's your twist. A malt-forward IPA. Great!

Flavor brings everything in that could be expected from the aroma, although it's a bit more bitter, even leaning on the metallic/steely side of bitter. Not in a bad way. Lotsa grapefruit buried under the malt. Everything is nicely balanced and earthy. Malt sweetness remains toffee-like and slightly burnt-tasting. Hops are grassy, citrusy and bordering on astringent. Butterscotch remains from the aroma, and the hops exert a nice green snap throughout the finish. With all that, it's the malt that remains the most impressive feature, as with the aroma. The malt serves as a savory, fairly complex anchor in what is a pretty big-tasting beer, never veering into the waters of messiness or, ironically enough, chaos.

Feel is a light, airy sort of thing, not thin or watery but certainly having the kind of incredibly easy glide that makes it too easy to drink too quickly.

I always enjoy the esoteric, even existential ramblings on the BrewDog labels, and I'm a definite fan of these guys in general, all their boundary-stretching and button-pushing is a good thing as far as I'm concerned. Chaos Theory is true to style, yet one that takes the road less traveled anyway. Nice work, fellas, this is intriguing.

Been trying all the Brew Dog I can get my hands on and these boys make some interesting beers. This one is a 22.4 ounce champagne bottle with some sediment at the bottom.

Appearance is a musty orange/amber with a soapy little head and some linear lacing that leaves a mark in memory of each sip.

The nose and taste is of sweet yet earthy hop nectar and biscuit malt. Very awesome example of English-style IPA. I've never really had one that excited me, but this one is very interesting! Can't really say its an authentic English version but I can say that I like it.

330ml bottle, served chilled (in the same glass I've been using for all my beer notes over the last week or so, I will dip into the collection and change things a little)

It pours with a rich, slightly hazy amber body. Whispy off white head soon settling to a modest half finger.

Not a huge nose, English hops beefed up with an almost pilsner-esque Sazz aroma. A touch medicinal but only very slight, some fruity notes too but nothing overpowering

On the palette. huge biscuity dry lingering hops. A whack of quinine and grapefruit acidic notes, followed by a lasting pleasing dryness on the finish. Backbone of pale malt with a touch of alcohol too. Not big on aromas but hugely hopped bitterness on the palette. Some esters lingering around the mouth punctuated by bills, ballsy bitterness

Pours a dark amber bordering on red, although again a rather minimal head.

As would be expected from an IPA, the nose was full of citrus, in fact it was very pungent, with a mix of Seville orange marmalade and bittersweet pink grapefruit. The contrast between bitter and sweet was to be a constant theme in the beer, the first taste being very bitter, and something of a shock if the truth be told, but subsequently it mellows out to reveal its jellied undertones.

As you would expect from this style it is very hoppy and the aftertaste reminded me of drinking an excellent single malt with a nice warming afterglow. The final few mouthfuls were syrupy sweet in a way that reinforced the jelly, an excellent beer overall.

T - Very similar to the smell. The fruits all hit you at the beginning with a nice clean bit of pine hops. The hop flavor escalates to a pleasantly bitter and flowery grapefruit rind all the way to the aftertaste.

M&D - Very smooth and easy to drink. The carbonation is Excellent for a bottled beer. More full bodied that many IPA's but not heavy by any means. I can (and will) drink a couple of these. My favorite Brewdog IPA.

Picked this up today @ Marty's in Newtonville. Batch 012 with BBD 8/16/2010. 500 ml into Portsmouth snifter. I would call this an American IPA rather than an English IPA because 1) the BBD is in American rather than European format (mm/dd/yy; not the real reason) and 2) the hop profile and forwardness with a bit of malt rather than a balanced or malt-forward profile fits the American IPA mold much better.

Man, I wish the carbonation on this would have a little more staying power. It's listed as a "copper IPA" and it definitely is. The eggshell, full-finger head looks solid...for about 5 seconds...and then it goes quickly, leaving those thin bubbly wisps. Not a lot of lacing on this one, but I'm struck by the clarity of it all.

The website says "insane hops." Well, they should move up the BBD then 'cause no way in hell these hops make it to 2010. But I really don't give a rat's ass, 'cause I'm checking this deal out now, and insane indeed. The pure grapefruit pulp reminds me of the Sculpin I had the other day. A slight hint of caramel and boozy sweetness balances this out very nicely on the nose. A pleasant surprise.

I do get the graprefruit on the taste but it is much more rind than pulp. The creamy caramel malt texture is still there and this is definitely a hop bomb. It works well and shows a fair amount of synergy; only beef is that the rind profile of the hops takes away from the clarity on the nose. Maybe they take a portion of their FWH or maybe their 60 minute and jack it down to 20 and 5 to show up a little more on the nose and less on the bittering. Still, this is quite enjoyable.

There is still the rind smashing the palate into oblivion. This shows a little disjoint with the caramel malt (crystal) and a little bit of slate and earthiness. Good and enjoyable but maybe not as tightly constructed as the top range of well-oiled (higher ABV) IPAs.

It's an enjoyable IPA with good synergy. Just enough malt to sit on the other side of the seeaw with these crazy-$#!+ "C" hops. Slight dryness keeps it clean. Finish has a bit of earth but not a huge amount. This is an enjoyable capper to have every couple of weeks - it smells like a rotating release but may be a one-shot deal...sort of like the "longshot" BBC contest. This is a prototype rather than a user recipe so let's hope it makes its way around each year or more frequently. Nicely done.

pours amber golden with no head and just a bit of lacing - for some reason all the brewdog beers i was sent were ridiculously flat - maybe a bad shipment? how does that happen

anyway, smell is so classic, hoppy goodness, so much grapefruit, citrus, piney hoppy gooeyness - really reminds me of a west coast ipa

taste is soo fruit hoptastic...not dry british at all...once again, grapefruit, even some ripe berries in there along with some lemon peel, finishes clean and smooth with a balanced bitterness - extra points in my mind just because its a british brewery doing a totally west coast usa IPA

Mouthfeel gets some knocks because of carbonation points...should be a bit more bubbly from a bottle...better in a cask perhaps.

summary - a great adaptation of a west coast ipa from brewdog, a UK brewer striving to make US style ales...boom, you did it, great beer!

A - Burnt siena brown body with a foamy cream-colored head that backs down to splotches along the edges.

S - Floral, fruity, and spicy. The fruit character is stone fruit all the way - peach and apricot. The sweet malt profile reminds me of layered, complex heather honey. Quaffable and unique - altogether a very accessible and enjoyable nose.

T - A touch of bitterness from the hops, but by and large the hop character manifests itself as fruity and floral. I find the flavor profile to be very balanced and well-layered - everything just sits well together. Alongside the mildly bitter finish, I am again reminded of the richness and complexity of a darker heather honey.

M - The carbonation in this brew is pretty spot-on. Just enough to lift the heaviness of the malt character off of the palate, leaving behind the more subtle and understated flavor notes.

D - I thoroughly enjoy this brew. It's a refreshing change of pace from well-hopped and well-malted beers that have no appreciation for subtlety. On a relatively unrelated note, I have no idea why this brew is called "Chaos Theory." The pseudo-didactic description of chaos theory on the bottle does little to illuminate why the folks at BrewDog have named this beer Chaos Theory. At any rate, do yourself a favor and find this brew, along with some Cabot Clothbound Cheddar, some good butter, and a freshly-baked loaf of white bread, and make a grilled cheese to eat alongside this delicious brew. I'm fairly certain that will be a meal that you will not regret.

This is an excellet, solid IPA, with firm, lightly complex flavour, and good balance.

Copper-amber, faintly hazy, it has a medium pale beige head that slowly shrinks to thin, frothy top and leaving a little nice, frothy lace.

Aroma is subdued but still characterful, with firm malty grain, fruity and jammy with citrusy hops leaning to the orange and marmalade. There is a hint of pine sap and herbal leafiness as well.

Taste is firmly malty, raisiny and lightly but clearly toasty and earthy with citrusy hops (bitter, burnt orange, orange zest, hint of grapefruit), hints of resin and herbal, leafy spiciness. Overall, bitterness and sweetness are balanced, with bitterness just taking over the finish slightly, with a briefly spicey bitter finish, before settling back into a lingering, balanced aftertaste with even bitterness and sweetness. Elements are integrated well and all hold up nicely. It has a light fullness with a hint of oiliness without relaly bieng oily.

A 330ml bottle with a BB of Aug 2011 (batch 232). A predictably random IPA - purchased quite a while ago but hopefully still in good condition.

Poured into a Sam Smith's pint glass. A hazy orangy-amber colour with good carbonation and plenty of visible yeast sediment. Yields a large head of creamy white foam that lasts for several minutes before subsiding to a decent surface layer. Smells hoppy, with lots of pine and citrus notes underpinned by light malt and earthy yeast aromas. Pretty good...

Very nice - a first-rate effort from Brewdog. More American IPA than English, but stands up to the US-brewed American IPAs that I've tried so far. The flavour is fantastically hoppy without being overwhelming, and the mouthfeel is excellent. Would definitely recommend this, although I'm not sure if it's still in production.

22.4oz bottle into a Duvel tulip at Flying Saucer pours a crisp dark orange with a decent khaki head that lasts and leaves spotty lacing on the glass. Aroma is a decent balance of sweet malts and funky hops. The taste is funky bitter hops up front with a nice malt backbone, very interesting and unique, quite tasty. The beer is medium bodied with a slight alcohol presence. This is a very enjoyable, unique beer.

I've had a few beers from this brewery and have been quite impressed. This one was not a let down either. The beer is a very clear amber color. The head is white and soapy, but it doesn't last long at all. The aroma has a very piney, citric (grapefruit and orange peel) aroma...lots of hops in this one. It's not one-sided, though, it also has a decided roasted and bready malt character. Good balance in the aroma (as well as the taste). The taste is predominantly bitter, with a great blend of hop and malt flavor. There's a little caramel flavor. Moderately sweet. Very firm mouthfeel and a medium body. The long and lingering finish is quite bitter. Good beer.

Taste And Mouthfeel: Firstly, Slight heat from the alcohol...then a sweet caramel taste comes out, followed by a mild hop note and settles with an almost peppermint flavor. The aftertaste on this is so refreshing...it's so sweet once it hits your lips!

Drinkability: This is a deceiving little one...you can barely taste the alcohol. It's quite refreshing and should be tasted. Now this is the sort of chaos I don't mind in my life!

In a pint glass this beer was an orange/amber color. It had a medium off white head, and a fair amount of lacing. Sweet malt aroma, very floral, and a bit of citrus. I caught more grapefruit in the taste, some pine, and a nice malt backbone. Slightly oily mouthfeel, balanced. Nice beer.

With all this news about BrewDog, I decided to try some of their beers out. (Marketing worked?! Actually, I have thought about buying their stuff before, and now that it showed up at my local store, I figured I'd give them try)

This bottle is larger than the one in the photo, 1 pint, 6.4 fl ounces. No batch #, best before 8/16/10.

Pours a nice bright and clear orange color with a solid white head.

Aromas are of brewed tea, cereal grains, and hints of citrus.

Flavors are good, and not overpowering. Some brewed tea up front, as well as soft creamy and toasted malt flavors. Finish is a bit dry, with an earthy hop bite.

Mouthfeel is nice and full, pretty smooth, but not overly heavy.

Drinkability is good. Pretty solid English IPA. I like how the malts and the hop flavors are nicely balanced. Pretty good stuff, I'd happily drink another one of these.
